Foam concentration measurement techniques

Three types of foam concentration measurement techniques are examined: total fluorine content, optical absorption, and specific conductivity. Specific conductivity was found to be the most useful for field measurements and was therefore compared with the traditional refractive index approach. It was found that electrical conductance provides a more accurate method of estimating the concentration of AFFF solution than does the refractive index technique described in NFPA 11.     

NFPA12标准下水电站发电机CO2灭火管路设计探讨

主要讨论了NFPA12标准下水电站发电机CO2灭火与国标水喷雾灭火方式的优缺点对比,以及发电机CO2灭火管路设计计算。随着社会和科技的发展,中国水电站会逐步实现无人值班,发电机灭火也会由水喷雾灭火为主,逐步改变为CO2灭火为主。     

Protecting fire fighters exposed in room fires,part 2: Performance of turnout coat materials under actual fire conditions

Seven experimental fires varying in fire load were conducted in a simulated townhouse. Specimens of various current fire fighters turnout coat materials were exposed in the room of fire origin. The time at which conditions would become untenable for the fire fighter due to pain, as well as the time to second degree burn, were calculated. These times ranked the coat specimens in roughly the same order as the Thermal Protection Performance measured according to NFPA 1971–1986, especially if the heat in the room developed rapidly.This paper is a contribution of the National Institute of Standards and Technology (formerly National Bureau of Standards) and is not subject to copyright.     

A design method for flaming fire detection

The scientific basis of a design method for the detection of flaming fires is reviewed. The equations required to calculate detector spacings are included and the selection of appropriate design input parameters is discussed. Limitations of the method and areas for further research are identified. The design method has been implemented and proposed for inclusion in NFPA Standard 72E-1984 as Appendix C by the 72E-M Committee. Center for Fire Safety Studies Worcester Polytechnic Institute
